This study reports that using stamps to mark scalp incisions with gentian violet ink and a barrier film improved incision symmetry and maintained slot visibility for hair graft insertion in the frontal region.

This study found that transplanting trichogenous dermal cells significantly enhanced the restoration of in vivo-damaged hair follicles in a nude rat model, with a combination of dermal papilla and sheath cells proving more effective than either cell type alone.

This review discusses the genetic and metabolic factors influencing hair pigmentation, as well as conditions leading to hypo- or depigmented hair, and reports no new experimental findings.

This study found that photodynamic therapy achieved permanent removal of nonpigmented hair in mice after multiple sessions, unlike laser treatment, which was not effective for nonpigmented hair.

This case report describes a patient with psoriasis who experienced scalp hair darkening and increased growth during anti–IL-17 therapy.

Pityriasis rubra pilaris is a rare skin disorder with reddish-orange patches and thickened skin, needing better treatment understanding.

This study describes a new mouse model for vitiligo that mimics key clinical features such as skin depigmentation and CD8 + T cell infiltration, providing a useful tool for in-depth research and drug discovery.

This study explored the diversity of melanocyte stem cell subpopulations in the hair follicles of adult female mice and identified novel groups with distinct immune privilege regulation, suggesting a heterogeneous landscape that future research should consider.

This study tested a microneedle patch on rabbit and pig models to support skin regeneration, revealing that the treatment accelerated wound closure, reduced scar formation, and promoted hair-bearing tissue and follicle growth, suggesting a trauma-guided framework for skin restoration.

This study found that Sox2 and BMP signaling may be key regulators of pigmentation and melanocyte migration, as suggested by experiments in mice, human biopsies, and cell co-cultures.

Combining MMP-9 and JAK inhibitors can effectively prevent skin depigmentation in vitiligo.

This study found that flavonoids with two hydroxyl groups in their B-ring, such as sterubin and luteolin, supported the regeneration of pigmented hair after skin injury, unlike those with one hydroxyl group.

This study found that Plerixafor, a CXCR4 antagonist, promotes melanogenesis in melanocytes by increasing MITF and tyrosinase expression and enhancing melanocyte migration, and it effectively restores pigmentation in a mouse depigmentation model without toxicity, highlighting its potential for treating pigmentary disorders.

This study found that non-vitiliginous melanocyte stem cells from vitiligo patients were unaffected by the disease and could effectively differentiate into melanin-producing melanocytes, suggesting their potential for use in cellular therapy for vitiligo repigmentation.

This study highlighted significant recent advancements in vitiligo transplantation surgery, improving graft orientation, donor-to-recipient ratios, and ease of technique in hair follicle transplants, alongside enhanced site preparation methods and improved procedural success rates.

This study found that MRL/MpJ mice heal burn wounds with scar formation, experiencing delayed wound closure and impaired myofibroblast development, which contrasts with quicker contraction in BALB/c mice.

This study examined dermoscopic features in African-American women with different types of alopecia and found that a perifollicular pink blush, potentially indicating inflammation, was common, particularly resolved with anti-inflammatory treatment, suggesting dermoscopy could aid in management.

This report describes three cases of erythromelanosis follicularis faciei et colli showing significant improvement in facial telangiectasia following treatment with a 595-nm pulsed dye laser, with minimal recurrence observed during follow-up.

This research reported that dermal progenitor cells can enhance split-thickness skin graft outcomes by improving dermal layer qualities and reducing itch and offer potential in skin wound healing using a flowable hydrogel for better cell delivery and survival.

This case report details a 21-year-old woman with dermatopathia pigmentosa reticularis, presenting with generalized reticulate hyperpigmentation, diffuse noncicatricial alopecia, onychodystrophy, palmoplantar keratoderma, and poorly developed dermatoglyphics.

Treatments for melanin disorders exist, but more effective options needed.

In this study, researchers concluded that Langerhans' cells are likely uninvolved in depigmentation during vitiligo in C57Bl/Ler-vit vit mice, as their numbers were normal during depigmentation and increased afterward.

This study demonstrated that combining AMD3100 with low-dose tacrolimus in a stem cell mobilization approach significantly reduced wound healing time and improved scar and hair follicle regeneration in full-thickness skin wounds.

This study suggests that newly developed micro-pigment-encapsulated biodegradable microneedles accurately implant pigments in pig cadaver skin, potentially advancing scalp micro-pigmentation methods.

Scalp micropigmentation usually needs two to three sessions, but factors like genetics, coverage area, and health conditions can require more.

Imatinib can repigment grey hair, while SU11428 can cause temporary hair depigmentation.

This study found that combining follicular unit extraction with topical calcipotriol betamethasone dipropionate showed the best repigmentation results in treating stable nonsegmental vitiligo.

This review discusses genetically-engineered mouse models for studying melanocytes and reports no new experimental findings; it emphasizes their potential to address unanswered questions in melanoma biology.

This research found that combining a 308-nm excimer laser with oral compound glycyrrhizin and topical 0.03% tacrolimus was more effective for treating pediatric facial and cervical vitiligo, resulting in faster and higher rates of repigmentation with minimal adverse effects compared to glycyrrhizin and tacrolimus alone.
